It's doubly tragic because (T2) diabetes is preventable, and even reversible in some cases. And I've read that T1 is also much better controlled on a low carb/ketogenic diet.

Prediabetes is broadly defined, it catches a lot of people who aren't necessarily going to become diabetic.

Let's not conflate Type 1 diabetes with Type 2 diabetes.

T1 is rare compared to T2, but those figures are still shockingly high.
